Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tubular type or a hollow structure i type with a liquid content of 1÷11.
This invention relates to a device for manufacturing a device by centrifugal casting.

A liquid separation device such as a reverse osmosis device or an ultrafiltration device can be used to separate the solvent and solute from the stock solution.

These liquid parts Ni11. As devices, tubular modules and hollow fiber modules are known. As shown in FIG. 1 (a3 and (b)), this tubular type module has a plurality of separation tubes 101 housed in parallel in a du-su 100.The separation tubes 101 are non-woven fabric tubes 102. A membrane lO,! is provided on the inner surface.The separation tube 101 is fixed in a liquid-tight manner by injection hardening resin 104 at both ends of the case 100.A piping joint is connected to both ends of the case 100 from the outside. The hollow fiber separation membrane 105 is attached with adhesive or screws.
(A plurality of membranes 5 are bundled and housed in an FRD-shaped case 107. Similar to the tubular module 7 described above, this separation membrane 106 is also fixed in a liquid-tight manner at both ends of the case 107 by injection hardening resin 108. It's modular.

The above-mentioned hardening resin one-finger injection step is one of the most important steps in assembling a liquid separation device. As a method for injecting this curable resin, there is known an injection method using so-called centrifugal casting, in which a module is installed horizontally and the resin is injected using the centrifugal force generated by rotating the module. According to this method, the space between the gastric portions 1i1 or the inside'! i! , fiber content 8
Since the gap between the 1G membranes is completely filled with resin and they can be completely liquid-tightly fixed without any voids, no liquid leaks from the ends of the separation tube or separation membrane.

By the way, when casting multiple modules at the same time 2.
Attempts have been made to connect a resin reservoir or pot provided at the center of rotation to each module end via piping, and to evenly distribute and inject the required H1 to each module end through this connecting pipe.

However, it is extremely difficult to inject the required amount of resin evenly into the ends of each module. Piping resistance 11
Although there are methods such as using M1 section, it is technically extremely complicated and impractical. If the same number of pots are arranged depending on the injection point, L can also be considered.

Since it is difficult to supply resin to the pot that rotates together with the module, a process called L must be carried out in which resin is supplied to the pot at the stop of two rotations and then operation is started. As a result, resin flows unduly into the module ends while reaching a predetermined centrifugal force. Since the module has not yet reached a predetermined centrifugal force, the resin that has flowed into the end of the module cannot stay at the end and unnecessarily flows out and adheres to the outside of the case and separation membrane.

J's purpose is 9. A predetermined amount of resin can be evenly distributed and supplied to each module end. An object of the present invention is to provide a manufacturing device for a liquid separation device. Another object of the present invention is to provide an apparatus for manufacturing a liquid separation device in which injected resin does not flow out or adhere to unnecessary parts of a separation tube, a separation membrane, or a storage case thereof. Still another object of the present invention is to provide an apparatus for manufacturing a liquid dispersion device that can be easily mass-produced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on its implementation and with reference to the drawings.

As shown in FIGS. 3(a), 3(b), and (1), the Kihatsu IJ4 device has a rotating body l and a rotating means M such as a motor for rotating the rotating body. l accommodates or fixes at least one wooden module lO to be resin-cast in parallel, and the longitudinal direction of the module 10 is the rotating surface.In this embodiment, the rotation +1 transmission surface is on the horizontal plane. /l/ 10 &; J: Pipe of specified length
Both ends of □-shaped separation tubes or hollow fibers No. 1 N15% 11 are closed by an appropriate method and loaded in a cylindrical case 12 in parallel. Covers 13 are attached to both ends of the case 12 to prevent the resin from leaking out after injection.

A pound 2 is fixed to the rotating body l.

Using the misfire FllJ device, a module of the liquid separator is cast in resin as follows: Both ends of a predetermined length of the equinox + S + L pipe or hollow fiber separation pipe 11 are closed in an appropriate manner, and the case 12 is closed. The resin leakage prevention covers 13 are placed on both ends, and the tube is then housed in the rotary body 1.Next, each discharge port 20 of the pot 2 and a predetermined portion of the module IO are connected via the rotary body 1 to piping. 5
Connect to each other. After confirming that the resin supply pipe valve 40 is "closed".

A required amount of curable casting resin R Venus is put into the resin tank 3. Next, the rotary body 1 and the pot 2 are rotated by driving the 2-rotation means M. When a predetermined centrifugal force is generated, the valve 40 is "opened" and resin is supplied into the bond 2 from the resin supply w4. The opening 400 of this supply pipe 4 is connected to the bond 2
Since the openings are offset from the center of rotation within the compartments, the supplied resin is supplied to each compartment rl, r2 . It flows down to ... sequentially and evenly.

Homogeneous resin flows into each compartment, and is further injected from the discharge port 20 of each compartment via the piping 5 into a predetermined portion I5 of the corresponding module by centrifugal force. Since the module rotates, the injected Jjil fat stays at the injection site and does not leak out or adhere to unnecessary areas. +711 Air bubbles in the fat move into the resin in module 1
No air bubbles remain in the casting resin because they diffuse toward the center of rotation along the 0 tubular snf tube or the hollow fiber separation 11Kjl.

Other embodiments of the device of the present invention are shown in Figures 1 and 4 (a2. and C). Rotate so that it is on the surface. Tree 1 leading from resin tank 3 to bond 2
The opening 401 of the bet supply pipe 4 does not need to be offset from the center of rotation of the pot, but it is necessary that it opens within the pot 2. Otherwise.

As in the case of the embodiment described above, it is injected through the pipe 5 into the predetermined region 15 of the corresponding module 1o. It is preferable to make the pot wall tapered and narrow in the direction of the pot opening 200 so that the resin contained in each compartment can completely flow out into the module IO. module/l/
The resin injected into the module 1o is rotated,
Therefore, it stays at the injection site and does not leak out or adhere to unnecessary areas.
